Handle Laravel 4 upload big file exception

extjs4, file-upload, laravel-4, php

Solution

There are two case: the file size is greater than the php variable `upload_max_filesize` and the second one is when it is grater than `post_max_size` variable. In the first one an exception is raised so an easy way it is catching it. In the second case there are not exception and I used this question for solving it.

Now, where check this code: in the Laravel controller aciton method. I thought that code in the controller's action never was excecuted, but I was wrong. So finally this is a way to solve this:

    public function upload_file()
    {
        $file_max = ini_get('upload_max_filesize');
        $file_max_str_leng = strlen($file_max);
        $file_max_meassure_unit = substr($file_max,$file_max_str_leng - 1,1);
        $file_max_meassure_unit = $file_max_meassure_unit == 'K' ? 'kb' : ($file_max_meassure_unit == 'M' ? 'mb' : ($file_max_meassure_unit == 'G' ? 'gb' : 'unidades'));
        $file_max = substr($file_max,0,$file_max_str_leng - 1);
        $file_max = intval($file_max);

        //handle second case
        if((empty($_FILES) && empty($_POST) && isset($_SERVER['REQUEST_METHOD']) && strtolower($_SERVER['REQUEST_METHOD']) == 'post'))
        { //catch file overload error...
             //grab the size limits...
            return json_encode(array('success'=>false, 'message'=>sprintf('The file size should be lower than %s%s.',$file_max,$file_max_meassure_unit)));
        }

        try{

            if (!Input::hasFile('file'))
                return;

            $utils = App::make('utils');
            $file = Input::file('file');

            $name = Input::get('name');
            $size = $file->getSize();

            if ($size > $file_max)
                return json_encode(array('success'=>false, 'message'=>sprintf('El tamaño del archivo debe ser menor que %smb.',$file_max)));

            $original_file_name = $file->getClientOriginalName();

            $destination_directory = "";

            $final_file_name = $utils->copy_file_to_location($file);       

            return json_encode(array('success'=>true, 'file'=>$original_file_name));
        }
        catch (Exception $e)
        {
            //handle first case
            return json_encode(array('success'=>false, 'message'=>sprintf('The file size should be lower than %s%s.',$file_max,$file_max_meassure_unit)));
        }
    }
